AZ: it's illegal for transgender people to use bathrooms of their preferred sex

>I want to stick said birth certificate into my purse and go to Arizona, and start pissing in the men's room everywhere I go.

If you found a few more dumb gender laws like this to exploit and went around obeying their letter it could make for good material for a documentary (might not be the best example but think Religulous).

Yep, nothing to do with the original bill. Arizona legislators have the ability to introduce "strike everything" amendments (first sentence of the amendment identifies this as what it is), which completely discard the text of an existing bill being considered and replace it with something else. This is usually done because (I believe) the process of replacing the text doesn't change where it is in the actual legislative process, allowing controversial bills to bypass parts of the process, or allowing legislators to reintroduce bills that were killed by previous votes.

I'm glad I like living in Arizona for plenty of other reasons.

Correct, it's only proposed.

On the other hand - I'm not sure which problem AZ is solving here. Maybe enough women weren't calling the police saying "there's a man in the bathroom!"
